Hi there, I’ve reviewed your project description for the EsoCore industrial IoT edge device and I can take on the full schematic capture, PCB routing, and documentation as required. With my background in mechatronics engineering and extensive PCB design experience, I’ve worked with STM32 microcontrollers (including the STM32H7 series), ESP32 modules, Ethernet PHYs, USB-C interfaces, PoE PD controllers, and multi-protocol industrial communication interfaces (Modbus, PROFIBUS, PROFINET). I use KiCad 8.x as my main EDA tool and have routed complex 4+ layer boards with high-speed signals (Ethernet, USB, SDIO), EMC/EMI protections, and safety-critical I/O. I also have hands-on experience with industrial standards (EN ISO 13849, IEC 61131) and protective circuit design (ESD, surge, isolation). A 100x160mm 4-layer board with these features is well within my capabilities — I typically deliver within a few weeks depending on review cycles and BOM availability. If you send me a message, I’d be glad to answer your detailed questions and share examples of similar industrial IoT hardware I’ve completed. Best regards, Samuel Tshibangu

Hi Dominik O., I recently completed a similar project. Message me so I can show you that sample. Q: For PLd safety I/O, are you targeting Category 3 with force-guided relays and EDM feedback? Please share PFHd budget, diagnostic coverage targets, and required creepage/clearance so I can size isolation (opto/isolated drivers), dual-channel cross-fault detection, and proof-test intervals correctly. Suggestion: Use a 4-layer EMC-robust stackup and partition: L1 signals, L2 solid GND, L3 split power (PoE PD/24V/3V3/isolated), L4 signals; star-point returns, keep PoE/DC front-end and relays in an “island” with 8 mm creepage, TVS + eFuse + common-mode chokes; length-match ETH RMII/USB, 100 Ω/90 Ω controlled impedance, Kelvin‑routed shunts for current sensing, and guard traces around H7 analog. Quick answers: - KiCad: Expert (8.x), custom DRC/netclasses, length-tuning, scripting (bom, fab). - STM32H7: Multiple H743 LQFP176 designs; VCAP/decoupling, SMPS vs LDO, boot/clocking, SDIO, FMC. - Protocols: Modbus RTU, PROFIBUS DP (isolated RS‑485, failsafe bias), PROFINET Device (RMII, PHY refclk, mag with PoE). - Timeline: 3–4 weeks schematic+layout, 1 week reviews/fixes, 1 week fab package. - Similar work: Industrial edge nodes with PoE (802.3af), PLd I/O, USB‑C service, SD logging, robust ESD/surge per IEC 61000‑4‑x. Kindly send me a message, lets discuss in detail and my portfolio is uploaded here and on my website. Best Regards, Sid CTO and Co-Founder of Ekarthaan
